We can form a system of equations:
x*y=90
and
x=2y+3.
Solving gives dimensions of 15 feet by 6 feet.
A graphing calculator shows the x-intercepts of the expression on the left to be -1, 4, 7.
The real solutions to the cubic equation are x ∈ {-1, 4, 7}.
Answer:
-32 :) is the answer just think about it as your adding the sum of these numbers then putting a negative in front of it.
Step-by-step explanation:
the whole exam will be 100%, and let's say that's "x" questions, but we also know that 9 is 60% of that so
